I noticed on WowArmory.com it has Aran's Soothing Sapphire as being a better upgrade for my Priest compared to Voodoo Shaker. If you vistit there and check it out you will see what I mean.

GoTo http://www.wowarmory.com and search the name Executed on the WindRunner server. Goto my Off-Hand and click the show upgrade button. Voodoo Shaker is quite a few down the list compared to Aran's Sapphire.
